generate a secure password in javascript

Question

What\'s the quickest way to generate a secure password in javascript?

I want it to contain at least 1 special character, and 2 mixed case. Must be at least 6 characters

Answer 1

 You could do some thing like below to generate password with following Requirements
    * At least One Special Character
    * At Least on Digit
    * At least on Upper Case
    * At least One Lower Case



function generatePassword(passwordLength) {
      var numberChars = "0123456789";
      var upperChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
      var lowerChars = "abcdefghijklmnopqrstuvwxyz";
      var specialChars = "#?!@$%^&*-";
      var allChars = numberChars + upperChars + lowerChars + specialChars;
      var randPasswordArray = Array(passwordLength);
      randPasswordArray[0] = numberChars;
      randPasswordArray[1] = upperChars;
      randPasswordArray[2] = lowerChars;
      randPasswordArray[3] = specialChars;
      randPasswordArray = randPasswordArray.fill(allChars, 4);
      return shuffleArray(randPasswordArray.map(function(x) { return x[Math.floor(Math.random() * x.length)] })).join('');
    }
    
    function shuffleArray(array) {
      for (var i = array.length - 1; i > 0; i--) {
        var j = Math.floor(Math.random() * (i + 1));
        var temp = array[i];
        array[i] = array[j];
        array[j] = temp;
      }
      return array;
    }
    
    //Change length accordingly
    alert(generatePassword(12));
